How Often Should An Air Purifier Be Used?

Indoor pollution level

Severe pollution: If the interior has just been renovated and there are pollutants such as formaldehyde that continue to volatilize, or if it is in an area with severe haze or there are pollution sources such as factories around, it is recommended to turn on the air purifier 24 hours a day, so that harmful substances in the air can be continuously purified and a relatively clean air environment can be provided for the room.

Mild pollution: If the indoor air quality is only slightly polluted, such as good daily ventilation, but occasional dust, etc., it can be turned on for 8-12 hours a day. It can be turned on during relatively heavy pollution periods such as haze days and after cleaning the room.

Usage scenario

Bedroom: People stay in the bedroom for a long time, especially when sleeping. In order to ensure sleep quality and respiratory health, it can be turned on in advance before going to bed and run all night, generally about 8 hours.

Living room: The living room is an area with frequent activities. It can be turned on during the time period when people are active, such as 6-8 hours when at home during the day, or during parties, when guests visit, etc.

Office: The working hours in the office are usually about 8 hours. It can be turned on during the working hours to provide fresh air for the working environment and improve work efficiency.

Air purifier performance

Efficient purification: If the air purifier has a high CADR value and strong purification efficiency, it can be turned on flexibly according to actual needs. It can quickly achieve a good purification effect without turning it on for a long time. It may be enough to turn it on for 4-6 hours a day.

Ordinary performance: If the performance of the air purifier is relatively average, in order to achieve a better purification effect, it may be necessary to extend the opening time, turning it on for 10-12 hours a day or even longer.

In addition, the long-term operation of the air purifier may cause too much dust accumulation on the filter, affecting the purification effect, and the filter needs to be checked and replaced regularly.

Is it better to turn on the air purifier for a longer time?

The longer the air purifier is turned on, the better it is. Although it can improve air quality, there are some disadvantages to turning it on for a long time. The specific analysis is as follows:

Advantages

Continuous air purification: For environments with continuous pollution sources, such as newly renovated houses, formaldehyde and other harmful substances are constantly released, or outdoor haze is serious, and frequent indoor activities produce more pollutants. Turning on the air purifier for a long time can continuously filter dust, pollen, smoke, bacteria and other pollutants in the air, so that the indoor air is kept at a good quality level, providing people with a healthier breathing environment.

Maintaining stable air quality: Turning it on for a long time can keep the indoor air in a relatively stable purification state, avoiding incomplete purification due to short-term opening, and large fluctuations in the concentration of pollutants in the air. Especially in places with high air quality requirements, such as hospitals, laboratories, precision instrument production workshops, etc., continuous opening helps maintain specific air environment standards.

Disadvantages

Accelerated filter loss: The filter of the air purifier will gradually accumulate dust and impurities in the process of filtering pollutants. Long-term use will make the filter reach saturation faster, reduce the filtering effect, shorten the service life of the filter, and need to replace the filter more frequently, increasing the cost of use.

Increased energy consumption: Air purifiers consume more electricity when running for a long time, especially some high-power products. Long-term operation will cause a significant increase in electricity bills, resulting in energy waste, which is not in line with the concept of energy conservation and environmental protection.

May cause noise interference: Although most air purifiers have relatively low noise when running, long-term continuous noise may still cause certain interference to people's lives and rest, especially during sleep. If the noise of the air purifier is loud, it will affect the quality of sleep.

Affect indoor air circulation: If you rely too much on air purifiers and close the doors and windows for a long time, it will cause poor indoor air circulation, increase carbon dioxide concentration, and relatively reduce oxygen content, which will make people feel chest tightness, dizziness, etc., which is not good for health.
